There are 2 small hole on the rotor, beside the stud hole that you install bolts into to remove the rotors, the rotors are iron and can not stand a hammer blow on the out side ring.. insert two bolts in the threaded hole and tighten envenly until the rotor pops loose( use a dead blow hammer if needed on the inside area only... <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
